President Obama’s endorsement of gay marriage last week did not sway voters in New Jersey, where 53 percent of voters support same-sex marriage and 67 percent want a voter referendum, according to a Quinnipiac poll released today.

The president’s announcement will make 19 percent of voters polled less likely to vote for him, and 16 percent more likely to vote for Obama. But 64 percent of voters said his endorsement won’t affect their vote, the poll said.

There’s an overwhelming age gap when it comes to gay marriage support, the poll found. Voters under 35 support it 77 to 18 percent, voters 35 to 54 support it 58 to 39 percent, and voters older than 55 are opposed, 53 to 41 percent.

“New Jersey voters approved of same-sex marriage before President Barack Obama evolved, and they still do,” said Maurice Carroll, director of the Quinnipiac University Polling Institute. “That 4-1 support among young voters shows this is just a matter of time.

Voters are divided on how gay marriage should proceed though, with 48 percent saying they want the legislature to override Gov. Chris Christie’s veto and 45 percent saying they don’t want an override.

The poll also found voters prefer a property tax cut over an income tax cut, 50 to 38 percent.

While Christie has pushed an income tax cut, Senate Democrats want a credit based on 10 percent of a resident’s property taxes. Although it appeared they had reached a compromise earlier this week, a press conference announcing the deal was abruptly canceled. Senate President Stephen Sweeney (D-Gloucester) said Tuesday he wants to get the Assembly on board with the plan as well. The poll was conducted before news of a compromise.
